On source parameters from particle correlations and spectra
Abstract
Analytic and numeric approximations are studied in detail for a hydrodynamic parameterization of singleparticle spectra and twoparticle correlation functions in high energy hadronproton and heavy ion reactions. Two very different sets of model parameters are shown to result in similarly shaped correlation functions and single particle spectra in a rather large region of the momentum space. However, the absolute normalization of the singleparticle spectra is found to be highly sensitive to the choice of the model parameters. For data fitting the analytic formulas are rephrased in terms of parameters of direct physical meaning, like mean transverse flow. The difference between the analytic and numeric approximations are determined as an analytic function of source parameters.
